Er1 Ru3

Er₁Ru₃ is an intermetallic compound combining erbium (a rare-earth element) with ruthenium in a 1:3 stoichiometric ratio. This material belongs to the family of rare-earth transition-metal intermetallics, which are primarily investigated in research contexts for their potential in high-temperature applications, magnetic devices, and advanced electronic systems. Er₁Ru₃ is not a widely commercialized engineering material; rather, it represents an experimental compound of interest to materials scientists studying the fundamental properties of rare-earth–ruthenium systems, particularly for applications requiring thermal stability, magnetic functionality, or catalytic behavior at elevated temperatures.
